Cisco 2620 Adding IPs

[soyarma]

I have a Cisco 2620 with a 64 IP Range set up on it. I didnt need to set up any routing to make this work, it just did. I just got another 64 IPs that are in a different class A ranges all together, and am unsure how to set the router up for these.

The subnets are both 255.255.255.192. The first range is from 0 - 63 and the new one is from 192 to 255

If anyone can give me an idea what I need to do I would really appreciate it. My external connection is a T1.

A couple of ways come to mind.. Subinterfaces or secondary IPs.. either will let you have the two ranges on a single interface without too much trouble.

interface serial 0
no ip address
encapsulation frame relay
!
interface serial 0.1
ip address 192.168.x.x 255.255.x.x

interface serial 0.2
ip address 192.168.x.x 255.255.x.x

Of course you have to tweak the example but it's just to demo how the subinterface would look.

So if my serial interface is currently 0/0 would I just do 0.1/0? there are already settings under 0/0.1 so I am unsure how I would do that. Thanks for the info though, that is a lot closer than I was before

No.. you would do serial 0/0.x If you already have a S0/0.1 then start with .2 or .3 or whatever. It doesnt have to be in order

Are these ip's supposed to be inside your network. I.E. are you assigning routeable ip's to your workstations ? generally your isp will give you a new subnet and you can simply add that ip as a secondary ip to your ethernet interface. could you send a screen shot (scrub it ofcourse) i have used the
"ip address 10.1.1.1 255.255.255.192 secondary"
before but not on a serial link as much as an ethernet interface. look forward to hearing from you!!
